摘　　要：根据分布式无线通信系统特点并综合考察网络范围内移动台路径损失、平均接收功率等性能指标,进行切换算法设计;利用OPNET仿真平台,对系统和算法进行了建模和等效处理,结合光载无线电技术参数对算法和模型等进行针对性修正,增加平均切换次数及最小接收功率等指标进行网络级仿真,验证了算法合理性并总结了理想状况下光载无线电网络的基本特性,提供了一种网络级分析的基本思路。According to the peculiarities of the distributed wireless communication system（DWCS） and the target parameters of the mobile node such as the loss of pass,the average of the received power,a switch algorithm based on network real-time performance is proposed.After the modeling and equalization of the system,the simulations are executed on OPNET platform.Considering the parameters of the radio over fiber（RoF） technique,the algorithm and model parameters alter to some certain extent,and the parameters such as the average switch times,the minimum of the received power are added to the simulating range.The simulations prove the rationality with a view from network lever.Some general conclusions of the RoF network are given,and a strategy of network simulation is provided as well.
